Go to the store and buy a fully wrapped fresh deck of standard playing cards. Have ten friends available to shuffle the new deck starting with person one through person ten, ten shuffles per person. At the end of those 100 shuffles, you’d probably agree that the deck is about as shuffled as it can be. Now place the deck on top of the table, all 52 cards face down. https://telugubiggboss.com

Now the question is, what is the value of the top card (or the 5th card or the 26th card or the 51st card) down from the top? Which card doesn’t matter; just choose one card in the one location.

Quantum physics will give you several possible scenarios.

Many Worlds Interpretation #1: You know, and I know, that the top card can be one of 52 possibilities. No one possibility is more or less likely than the next. So, since there’s nothing that favours one card over another, when the top card is turned over, all 52 possibilities eventuate. That’s accomplished because the cosmos divides into 51 further universes. In our Universe, one card will eventuate as the top card. Since there are 51 other possibilities, all equally possible, each one happens in each of the 51 new universes. There is no favouritism.

The issue of credibility comes into play when you realise that throughout our entire universe, zillions of ‘forks in the road’ decision or option branches happen each second. Thus every second zillions of new universes have to be created in order to give each and every possibility a fair go. Considering how many seconds have elapsed in our universe in the past 13.7 billion years, well that’s a tad more newly created universes than you can count on your fingers and toes! Further, each newly created universe, a branch-off of ours, in turn generates zillions more universes each second, each of which creates zillions more each second, and so on and so on.

The ‘many worlds’ tag isn’t quite ‘infinite worlds’, but the number of universes present and accounted for is several orders of magnitude larger by now than ‘many’ would suggest. The good news is that in one universe, all of those ‘forks in the road’ over all the millennia have been by chance allowed you to become Master of the Universe – well that specific universe anyway!

Many Worlds Interpretation #2: The other side of the Many Worlds coin is that from the get-go there already exists all those other 51 universes, each with a new deck of cards shuffled 100 times. In those 51 universes plus our own, all top card possibilities are realized. Of course that means that in the beginning there were all those zillions and zillions and zillions of universes each one having its own unique cosmic history. When all are put together, everything that can happen does happen, so all possibilities get a fair go and thus their moment of glory basking in the sunshine.

Copenhagen Interpretation: In this scenario, as above, all you and I know is that the top card is one of 52 possibilities. In the Copenhagen Interpretation, not one of those 52 possibilities is really real until such time as someone peeks. Options all exist equally and simultaneously until then. That’s called the wave-function – it’s a measure of probability. It’s the very act of observation or measurement (same difference) that gives rise to a single and unique reality. That’s termed the collapse of the wave-function. No observation, therefore no reality, just a superposition or a composite of all possible realities. [Actually the entire deck is in a state of ever shifting superposition since the value of every card is undetermined.] The problem here is that how is it that the lucky card becomes the lucky card and the other 51 possibilities go ‘poof’ into the realm of unreality. One card lives; 51 cards die without rhyme or reason.

The other problem is that when it comes to ‘forks in the road’, the universe has made the reality/unreality decision zillions of times without there being anyone around to peek, make a measurement or an observation. Taken to its logical conclusion the Copenhagen Interpretation suggests that the Universe exists and has tangible reality because observers exist. Without observers (life) the entire Universe would be in just one superposition of all possible states simultaneously. So, the question is, is an observer really necessary in order for a state of probabilities to become one actual reality and hence other possibilities achieve unreality? If not, and it would appear that’s the case since the universe hasn’t always had peeping-toms, the Copenhagen Interpretation is kaput. The Universe did nicely without observers (life) for billions of years. Observers are nice but unnecessary.

Common Sense Interpretation: Forget quantum probabilities. Causality rules, OK? If you observe all the variables that went into all the shuffling of that deck of cards, each and every one was grounded in cause-and-effect. If you filmed the entire shuffling sequence in high speed motion, then played back the film frame-by-frame, by knowing the original sequence of the brand new deck, you should be able to determine what the top card was after those 100 shuffles. There is no probability involved. Okay, even if you have no idea what the top card was after 100 shuffles, it is fixed and certain. The top card is not a composite of all 52 possibilities. Whether the top card is turned over seconds after that final shuffle, or 1000 years later, the value of that top card will be the same. Unfortunately you won’t tend to find this kind of explanation in the textbooks as any association between quantum physics and causality is frowned upon.
